LATHE eon TURNING AXLES.

I no. 325,614.

zen of theUnited States, residing at Newton turned orshaped may be Upper Falls, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Im rovement inLathes for Turning Axles, of w ich the following is a full, clear, concise, and exact description, reference being had to. the accom anying drawings, forming a part of this spec cation.

My invention relates to improvements in lathes particularly designed for' turning'axles or articles of a similar nature.

' One of the objects of my invention is to provide a lathe in which the articles tobe assed endwise into position, so V as to fac' itate the han-. dling of such articles. 1 v

Another object of my invention is to produce a'lathe which will have special features of construction which will add to its utility.

With these and other objects in view I have designed the device shown in the accompanying drawings, which illustrate one embodiment of my invention, the several views of said drawin s being as follows: 1

Figure 1 is a side e evation of my improved lathe. Fig. 2 is an end view thereof. .Fig. 3 is a side elevation of a modification. of'my invention, and Fig.4 is an end view of sa d modification. a

Throughout the drawings like reference characters designate similar and correspond-- in parts. v

11 said drawings is showna bed 1, of any suitable form, mounted upon legs 2. Upon the top of the bed-plate1s arrangeda suitable su(pport or bearing 3, which is preferably secure port is journaled a cylinder or barrel 5, which is provided with a gear 6 for rotating the same. The opening through said barrel is of suitable shape to receive the article to be turned, and screws 7 are provided forclampingsaid article torotate with said barrel] J ournaled in suitable supports 8, mounted uppn the rear of the bed, is'adriving-shaft 9,

ch carries pulleys 10 and 11 for driving said shaft. A back shaft 12 is journaled in the support 3 and carries a gear .13, which meshes with a pinion 14 upon the drivin'g shaft. Also mounted onsaid back shaft is a pinion 15, which mesheswith the gear 6 u on the revoluble cylinder or barrel journale in Specification of Letters faten't. rpllmiontloi :5'16, 1903. sarmraimo'a I I .1

the support 3-. By this arrangement of gear ing the revolublebarrel 5 is rotated from the driving-shaft. At each end of the-bed. is slid ably mounted a tool-carriage 17, which is moved along the bed by the usual mecham ism. Each tool'carriage is provided with a tool-support 20, which is adjustable by a hand-wheel 21. The tool' for turni the article being shaped by the lathe, as s own in the drawings, is clam edinposition on the I 'ch' is bolted in position-by bolts 24.

,At each end of the lathe is preferably arranged a plurality of foot-stocks 25, which are preferabl all formed integral on a single hub 26, whic is journaled u on a mandrel 27,projecting from the end 0 the bed.. The several foot-stocks at each end preferably extend radially from their hub, and openings or spaces are provided between said foot-stocks. The hub of the foot-stocks is ke t in position on. the mandrel preferably by a ate 28, which is secured to said mandrel b rotating the several foot-stoc theymay successively 'be brou ht opposite the center of the lathe, and suita le mechanism may be rovided for locking any one of the foot-stocl s in position opposite the center of the'lathe B center of the lathe or lathe center wish to be understood as meaning the rotary axis of the work. I It will be understood that one or any num-- ber 'of foot-stocks may be pivoted out of alinement with the lathe center, a's'above described, or such foot-stock or foot-stocks may be arranged in any suitable manner to ermit the same tobe brought opposite the athe center when operating upon the article to be turned andto be removed therefrom "olts 29.- By

ines an axle It will be observed linder at the center of the lathe and i c c utched therein by the screws 7. By bringing the space between an two of the foot-stocks opposite the center 0 the lathe the axle may be withdrawnendwise from the lathe, or if. it

be desired to place an axle in position a similar location ofv one ofsaid spaces will ermit the this way the necessity of placing the axle in the lathe laterally is obviated, and by pro- .10 axle to be placed in the lathe. en wise. In.

viding each end of the lathe with foot-stocks of the character described the axles or other articles which it is desired to shape may be placed in the lathe endwise from one end and withdrawn endwise from the opposite end. In this way the handling of the axles in shaping the same may be materially facilitated. The several foot-stocks preferably each have an adjustable spindle 30, which is provided with a hand-wheel 31 for operating the same. The spindle of each of the foot-stocks (shown opposite the center of the lathe in Fig. 1-) is provided with a center 32 for supporting the axle. The several foot-stocks at each end of the lathe may be provided with a different tool for erforming various operations in shaping t e axle. The foot stock at the lower ri lit-hand corner of Fig. 1 is shown as provided with a drill, and the foot-stock at th lower left-hand corner of Fig. 1 is shown as arrying a tool for shaping the end of the axle. Any number of foot-stocks may be employed and as many tools carried thereby as may be deemed desirable, and each of said foot-stocks'may be brought opposite the center of the lathe and the tool carried thereby operated to perform its function. The several tools, such as the shaper or the drill, may be rotated from the back shaft by gearing or other suitable means when they are in position to operate upon the axle, or the axle itself may be rotated and the tool remain stationary.

In the operation of thedevice shown in Figs. 1 and 2 of the drawings the foot-stocks at one end of the lathe are rotated to bring the space between two of said foot-stocks o posite the center of the lathe, and then t e axle is passed between said foot-stocks into position on the lathe and clamped to the barrel or cylinder at the center of the lathe by screws 7. Then said barrel is operated to revolve the axle, and while the axle is revolving the shaper carried by one of the footstocks is brought opposite the center of the lathe by revolving t e foot-stock on whlch it is carried. Said shaper is now brought in contact with the end of the axle and turns the end thereof into the desired form. Next,

the drill carried by one of the foot-stocks is brought opposite the center of the lathe and a hole dr' led for the insertionof the center carried by either one of the foot-stocks. After this hole has been made the tool is removed and the foot-stock carrying the center is brought into the position and the center inserte in said hole. These operations are performed at each end, and when the centers are inserted in their respective holes at the opposite ends of the axle the tools supported by the tool-carriages are moved into position to turn the periphery of the axle into the desired shape. Any number of foot-stocks may be provided and any tools WhlCh are suitable to accomplish the desired purpose may be employed, and, furthermore, the operation of said tools may be effected in any manner which may be deemed desirable. As above stated, suitable locking mechanism may be provided for fastening any one of the stocks in position opposite the center of the lathe.

In Figs. 3 and 4 I have shown a modification of my invention. In said modification is shown a bed 33, supported on legs 34, as the preferred form of my invention, and upon the top of said bed is secured a support 35, in which is journaled a barrel 36, having bolts 37 for clamping the article to be turned to said barrel. This barrel is provided with a gear 38, with which meshes a gear 39. The gear 39 is mounted upon a back shaft 40, which is suitably journaled in the su port 35 and in brackets 41, secured to t e base. This back shaft 40 also has mounted thereon pulleys 42 for turning the same. At each end of the bed is arranged a bearing box or support 43, in which is revolubly mounted a cylinder or barrel 44. This barrel or cylinder is provided with an opening 45, which may be brought opposite the center of the lathe to permit the articles to be passed endwise into position on the lathe. Said barrel also carries a plurality of spindles 46, one of which is shown as provided with a drill 47 and the other with a center 48. Each spindle is adjustable in the barrel, and a hand-wheel 49 is associated with each of said spindles for operating the same. Each of said spindles is disposed at a position on said barrel which permits the same to be brought 0 osite the center of the lathe when the barre is rotated, and a hand-wheel 50, provided with a screw 52, adapted to engage the periphery of said barrel and threaded in the bearinwbox 43, is provided for locking said barrel in any desired position, so that when the several tools are brought 0 posite the center and are in use they may be rmly held in place.

A train of gears 53 is illustrated in the modification of my invention for imparting rotary movement to the drill, and said train of gears is operated from a ear 54, mounted upon the back shaft. In t 's construction, as in the construction shown in the preferred embodiment of my invention, the axle or other article to be turned may be passed endwise into osition and also removed endwise from the athe by bringing the hole 45 in the barrel or cylinder 0 posite the center of the lathe. By havin harrels of like construction at each end 0 the lathethe axle may be passed endwise into position and then shaped and finally removed endwise through the hole in the barrel at the o posite end of the lathe. After an axle has een placed in position on the lathe in this construction of my device the same may remain in a stationary position and the drill brought op osite the same and rotated to make the ho e for the center,- and after said hole has been formed the drill is removed and the center brought into position. 1

Certain gears of the train for operating the drill are arranged to be separated, except when the tool is in position, and therefore said drill is only rotated when it is opposite the center of the lathe. As in my other construction, 'any number of s indles maybe employed and any form of too s may be utilized.

I Many changes may be made in thedetails of construction herein shown and described without in any way departing from the spirit of my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is. r
